Glass disc insulators are essential components in power transmission and distribution systems. They are designed to provide reliable insulation for overhead transmission lines and substations, ensuring system efficiency even in harsh environmental conditions. Yipeng, a trusted supplier of glass disc insulators, offers a wide range of products tailored to meet customer requirements across various industries. With years of research and development, our glass insulators can operate in up to 1000 kV, providing unmatched reliability and performance.
High Mechanical Strength: Glass insulators are less prone to surface cracks, ensuring longer service life compared to porcelain insulators.
No Aging: Unlike porcelain, glass insulators maintain their electrical strength throughout operation, with slow aging, reducing the need for frequent replacements.
Easy Damage Detection: When damaged, glass insulators break into identifiable shards, allowing operators to easily detect and replace them.
Self-Breakage Feature: Glass insulators exhibit a "zero value" self-detonation, providing extra safety. Even after self-damage, the residual part maintains good tensile strength.
Standard Type Glass Disc Insulator: Performs well in mild pollution environments, making it suitable for general use in power transmission systems.
Fog Type Glass Disc Insulator: Ideal for regions experiencing high humidity and fog, offering superior performance in such conditions.
Open Type Glass Disc Insulator: Designed for desert areas with high temperatures and sandstorms, ensuring long-lasting durability.
Glass Disc Insulator with RTV Coating: With the growing pollution in many areas, RTV-coated insulators are increasingly preferred for their enhanced performance.
Glass disc insulators with RTV (Room Temperature Vulcanizing) coating offer several unique advantages, especially in areas where pollution and environmental stress are significant concerns. These insulators are engineered to provide:
Resistance to Tracking and Erosion: RTV-coated insulators are resistant to tracking, ensuring long-term operational reliability.
Prevention of Light Pollution: These insulators reduce the occurrence of light pollution, which can be problematic in urban and industrial areas.
Resistance to Weathering & UV: The RTV coating offers excellent protection against weathering and UV radiation, extending the life of the insulators.
Resistance to Chemical & Physical Degradation: These insulators can withstand chemical and physical degradation, including damage from water.
High Volume Resistivity: Ensures minimal electrical leakage and efficient insulation performance.
Resistance to Corona & Ozone: The RTV-coated glass insulators prevent corona discharge and ozone-related degradation.
